I had to look this up. It seems that Frank Tipler has taken hold of Teilhard de Chardin's metaphysical idea of the "Omega Point" and extended it, with some rather bogus quantum mechanical arguments. Teilhard de Chardin, being a Jesuit, had this idea that the cosmos was teleological and tended towards development of higher and higher degrees of consciousness (the "noosphere"), culminating in the Omega Point, which he more or less identified with God. (I simplify.) Tipler has built up, from the notion most physicists now think is daft, that wave function collapse requires a conscious observer, a theory that there must be some ultimate conscious observer. Or something - I got a bit bored trying to disentangle it.
